The massive outbreak, which seemed to result in increasing amounts of ghostly activity day-by-day, was investigated by seemingly the combined forces of every agency within England, with the sole exception of Lockwood & Co.. However, following Lockwood & Co.'s favorable showing at handling a disruption to a party held to calm the public tensions, Lockwood & Co. was invited to investigate as well.
They, along with the help of Quill Kipps and his team from the Fittes Agency, traced the problem to the Aickmere Brothers department store, where they encountered a powerful poltergiest and the results of a strange experiment underground. It was later determined that the strange experiment was the doing of the Rotwell Agency, who had also been engaged in a number of other unusual and forbidden activities.
